Description

Integrative cold pressing section bar of photovoltaic frame

Technical Field

The utility model belongs to the field of photovoltaic profiles, and relates to a photovoltaic frame integrated cold-pressing profile.

Background

The existing photovoltaic panel usually adopts an annular section bar made of a thin-wall metal material as a frame bottom support, but because the weight of the photovoltaic panel on the section bar in a large batch is large, the conventional annular section bar only depends on the bearing force of a bottom U-shaped structure, the whole bearing load is limited, and the vertical outer walls on two sides are bent and deformed outwards or inwards horizontally due to the overpressure force of the annular section bar.

For example, chinese patent literature discloses a high strength steel cold-formed profile [202122813907.8] for photovoltaic module rims, comprising an outer side and an inner side. The outer portion has a large U-shaped portion arranged horizontally with the mouth facing inward. The inner portion has a small U-shaped portion. The small upper vertical wall and the small transverse wall of the small U-shaped part are respectively abutted against the upper parts of the large upper vertical wall and the large transverse wall of the large U-shaped part. An L-shaped part is arranged below the small U-shaped part, and the upper edge of the vertical wall of the L-shaped part and the outer edge of the small lower vertical wall of the small U-shaped part are of an integrated structure. Thereby a cavity is defined by the small lower vertical wall of the small U-shaped part, the large lower vertical wall of the large U-shaped part, the vertical wall of the L-shaped part and the large transverse wall of the large U-shaped part. The method is characterized in that: welding points are uniformly distributed between the small transverse wall of the small U-shaped part and the large transverse wall of the large U-shaped part in the longitudinal direction. The outer edge of the large lower vertical wall of the large U-shaped part is provided with an extension edge, and welding points are uniformly distributed between the extension edge and the longitudinal direction of the transverse wall of the L-shaped part. The section bar has the advantages of good structural rigidity, high strength, low production cost and capability of prolonging the service life of the photovoltaic module, but has poor supporting and bearing capacity and larger lifting space.
